java中如何把ResultSet的结果集转换成一个二维数组

首先你的用一个sql语句：select count() from customer 取到符合条件记录的数目；
String lSqlStr = "select count() from customer";
…
int lCount = rs.getInt(1);
String[][] lRecordArr = new String[lCount][3];
//其中3是你的字段数customerID,customerName,customerInf

String selectCustomer=select customerID,customerName,customerInf form customer;
…
rs=st.executeQuery(selectCustomer);
int i=0;
while(rs.next())
{
lRecordArr[i][0] = rs.getString(“customerID”);
lRecordArr[i][1] = rs.getString(“customerName”);
lRecordArr[i][2] = rs.getString(“customerInf”);
i++
}
